Introduction
The Oklahoma Tax Commission (OTC), in conjunction with the Internal Revenue Service (IRS),
began accepting Oklahoma Corporate Income Tax returns and corresponding forms for tax year
2009 by method of the Modernized e-File system (MeF). At this time Oklahoma will only accept
C-corp returns (Form 512). Corporations filing as an S-corp (Form 512-S) must file by paper.
The transmission method is a Web Service using Simple Object Access Protocol (SOAP) with
attachments messaging. The return data is formatted using Extensible Markup Language (XML).
Authorized E-File providers, also known as Electronic Return Originators (ERO’s), can submit
returns to the IRS MeF system for Federal and state return processing. The State submission can
be transmitted as a “linked” return (also referred to as a Fed/State return) or as an “unlinked”
return (also referred to as a State Standalone return). Each return (Linked or Unlinked) must be
in a separate submission. Multiple submissions may be contained in a single message payload.
Software developers must test with OTC prior to submitting live Fed/State or State Standalone
returns.

Changes to 2010 Income Tax
Taxable Income:
Captive real estate investment trust (REIT) –
􀂾 Requires the add-back of the dividends-paid deduction otherwise allowed by federal law in
computing net income of a captive real estate investment trust (REIT).
􀂾 A corporation no longer has to add back rents and interest expenses paid to a captive REIT,
if the captive REIT is filing an Oklahoma return and is required to add back the dividends
paid deduction.
The measure prevents the misuse of the REIT structure as a means to escape corporate income tax
laws, but avoids any unintended consequences.
Income from Discharge of Indebtedness Add-back – Income from discharge of indebtedness
deferred under Section 108 (i)(1) of the Internal Revenue Code, as provided for in the American
Recovery and Reinvestment Act of 2009, must be added back to compute Oklahoma taxable
income. Such income will be deducted from Oklahoma taxable income when ratably included in
Federal income over five subsequent tax years.
Credits:
Credit for Wire Transfer Fee – A credit is allowed for the electronic funds transfer fee paid
pursuant to the Drug Money Laundering and Wire Transmitter Act (Title 63 O.S. Section 2-
503.1j). Taxpayers will claim the credit for all fees paid during tax years 2009 and 2010 on their
2010 tax return. Any credit allowed but not used will have a five year carryover provision. Upon
request you must be able to document the amount of fees paid upon which the credit is based.
Credit for Manufacturers of Electric Vehicles -
Establishes a credit for the manufacturer of low-speed electric motor vehicles, medium-speed
electric motor vehicles or electric motor vehicles which are manufactured after June 30, 2010.
The manufacturer must have a manufacturer exemption permit. The credit will be as follows:
• For low-speed electric motor vehicles the credit is $500 per vehicle manufactured.
• For medium-speed electric motor vehicles the credit is $1,000 per vehicle manufactured.
• For electric motor vehicles, which are not low-speed or medium-speed vehicles, the
credit is $2,000 per vehicle manufactured.
Any credit allowed but not used will have a five year carryover provision.
Credit for Investment in Qualified Electric Motor Vehicle Property – Establishes a sunset date for
the Credit. No credit will be allowed for investments in qualified electric motor vehicle property
placed in service on or after July 1, 2010. Extends the unused carryover provision from 3 years to
5 years on qualified investments made during the period January 1, 2010 through June 30, 2010.
See Form 567-B
Credit for Investment in Clean-Burning Motor Vehicle Fuel Property – Several amendments have
been made to the credit, among them are:
• Hydrogen has been added as a qualified fuel, but for tax year 2010 only.
• Methanol and “M-85” are no longer considered qualifying fuels.
• The credit, for property directly related to the delivery of a qualified fuel into the fuel
tank of a motor vehicle and the storage of such fuel, increased from 50% to 75% of the
cost of the qualified property.
• Adds a credit for a public access recharging system for vehicles propelled by electricity
equal to 75% of the cost of the qualified property.
4
• Adds a credit for a natural gas refueling station in a private residence equal to the lesser
of 50% of the cost of the qualified property or $2,500.
• Extends the unused carryover provision from 3 years to 5 years.
See Form 567-A
Credit for Tourism Development or Qualified Media Production Facility
􀂾 The definition of “tourism attraction” was expanded to include a destination hotel whose
location and amenities, including but not limited to upscale dining, recreation and
entertainment, make the hotel itself a destination for tourists.
􀂾 The amount of the credit was modified to up to 10% or up to 25% of approved costs, but will
be limited to the percent of the approved costs that will result in the project being revenue
neutral to the State as determined by the Oklahoma Tax Commission. Previously, the amount
of such credit was 10% or 25% of approved costs. Revenue neutral means the amount by
which increased tax revenues from the tourism attraction project or the film, digital media or
music production and development facility will exceed the credit.
􀂾 Proof of expenditures is required prior to the Tax Commission issuing a tax credit
memorandum to the approved company which may be satisfied by a report from an
independent certified public account.
Tax Credit Moratorium
A Tax Credit Moratorium has been placed on many Oklahoma credits. For more

Acceptance and Participation
EROs and transmitters must be approved with the IRS in order to submit Fed/State or State
Standalone returns. You do not need to register with the Oklahoma Tax Commission. Upon IRS
approval for electronic filing, you are automatically approved for Oklahoma.
Software Developers must register by completing Form D-104 “Software Developer Information
Sheet For Electronic Filing of Corporate Income Tax Returns (Form 512)”. You will receive a
confirmation that we have received your information. Once you have received the confirmation
you may then transmit your test returns. You may download test returns from our website
www.tax.ok.gov under the Developer/Preparer Info link.
7
Types of Returns Accepted
• Linked (Fed/State)
The Federal and state submissions do not have to be transmitted to MeF together. A state
submission can be linked to the Federal submission by including the Submission ID of the
Federal return in the state manifest. If the state submission is linked to a Federal submission (also
referred to as a Fed/State return), the IRS will check to see if there is an accepted Federal
submission under that Submission ID.
If there is not an accepted Federal return, the IRS will deny the state submission and an
acknowledgement will be sent. Oklahoma will have no knowledge that the state return was
denied (rejected ) by the IRS.
If there is an accepted Federal return under that Submission ID, then the IRS will do minimal
validation on the state submission and pass along to the state what the ERO/Transmitter sends in
the State submission. Oklahoma will generate the acknowledgement for the Oklahoma return and
send it to the MeF system for the transmitter to retrieve.
• Unlinked (State Standalone)
If the ERO/Transmitter does not link the state return to a previously-accepted Federal return (also
referred to as State Standalone), the IRS will perform minimal validation and will pass along to
the state the entire state submission that was sent in by the ERO/taxpayer. The state return is
made up of the Oklahoma return and applicable Federal return; the taxpayer is required to provide
both components. Oklahoma will generate the acknowledgement for the Oklahoma return and
send it to the MeF system for the transmitter to retrieve.
8
What Can be Transmitted Electronically
The Oklahoma electronic return will consist of data transmitted as well as supporting PDFs. In
total, an electronic return contains the same information as a comparable return filed entirely on
paper.
The following is a list of all of the XML forms that Oklahoma accepts electronically. Software
Developers are not required to support all of the supplemental forms that Oklahoma accepts
electronically.
Income Tax Return
• Form 512 - Oklahoma Corporate Income Tax Return
Supplemental Forms
• Form 512-TI – Computation of Oklahoma Consolidated Taxable Income
• Form 511CR – Other Credits Form
• Form 561C – Oklahoma Capital Gain Deduction for Corporations Filing Form 512
• Form 506 – Investment/New Jobs Credit
Note: Any of the above supplemental forms that a Developer does not support as XML data
should be attached as pdf documents.
Attachments to the Electronic Return
The tax return may also include non-XML documents, known as “binary attachments”, submitted
in PDF format. These attachments include items from the following sources:
• Form/Schedule not supported – any Oklahoma forms or schedules which are required
to be filed with the return, but not supported in XML format.
• Supporting documentation – any supporting documentation required to be submitted
with a form.
• Additional information – any additional information that needs to be filed with the
return.
Approved MeF tax preparation software should provide the necessary instructions for creating,
scanning or exporting documents in PDF format and submitting these documents as attachments
that are required by Oklahoma and IRS publications, Code, and/or Regulations. Preparers will
create the binary attachments as pdf documents and submit them as electronic files attached to the
MeF return. Check with your software provider to see if your software will support binary
attachments.
9
Copy of Federal Return Required
The complete Federal return and the necessary supporting schedules as submitted to the IRS are
required to be submitted in XML and PDF format along with the Oklahoma return. If the
taxpayer is included in the Federal return of a consolidated group, a copy of the pro-forma
Federal return for the company must be included along with the first four pages of the
consolidated Federal return and the consolidating income statement, balance sheet and schedule
M-1/M-3 including applicable detailed schedules.
What Cannot be Transmitted Electronically
Oklahoma follows the IRS guidelines for MeF exclusions (Refer to IRS Publication 4164). In
addition to the IRS guidelines, the following types of returns are excluded from electronic filing:
• Amended returns
• Subsequent return beginning in same tax year – Oklahoma will only accept one return
each filing season, any subsequent filings such as an additional short year return must
be filed by paper.
• Returns for a tax year prior to 2009. You must pass testing in order to e-file prior year
returns.
• Filings that are a duplicate to a paper filed return.
• Returns with cent entries
Signature Document (Form EF)
The Form EF must be completed and signed by all required parties.
• The original is to be retained by the ERO, along with a copy of the e-Filed return, for 3
years and made available to the Oklahoma Tax Commission upon request. All EROs will
be subject to periodic reviews by the OTC to ensure the paperwork is being retained.
• The taxpayer must be provided with a copy of the Form EF along with documentation of
all completed Oklahoma forms and schedules filed for the taxpayer. This documentation
may be furnished on official Oklahoma forms, on copies of official forms, or on software
designed forms that have been approved by the Oklahoma Tax Commission.
Entry of the Taxpayer’s Personal Identification Number (PIN) in the electronic filing
process operated by the IRS shall service as an “electronic signature”. Entry of the
taxpayer’s PIN as signature will only be allowed on a linked (Fed/State) electronically-filed
return. Use of a PIN will not be allowed on an unlinked (State Standalone) return.
10
Acknowledgement System
Oklahoma generates an acknowledgement of acceptance for all returns received. Oklahoma does
not reject e-Filed returns. If an electronic acknowledgement has not been received within 48
hours of our scheduled retrieval process for any transmitted return, the ERO should contact
Oklahoma’s E-File Coordinator for further instructions. It is the responsibility of the ERO to
ensure that every return filed electronically is acknowledged as accepted.
Timeliness of Filing
All prescribed due dates for filing of returns apply to MeF returns. If any due date falls on a
Saturday, Sunday or legal holiday when the Oklahoma Tax Commission’s offices are closed, the
return must be filed by the next business day.
The receipt of an electronic postmark will provide taxpayers with confidence that they have filed
their return timely. When the date of the electronic postmark is on or before the prescribed due
date but the return is received by Oklahoma after the due date, the date of the electronic postmark
is considered the date of filing.
11
Balance Due Returns
Taxpayers who file their return electronically can elect to pay their balance due by four different
methods. The taxpayer is responsible for paying the amount due to the OTC when a return is filed
or no later than the original due date.
• Direct debit (electronic funds withdrawal), for a full or partial payment when filing their
return and choose an effective date.
Taxpayers may have their payments directly withdrawn from their checking or savings
account. The bank routing and account numbers, the amount to be withdrawn and the
date the funds are to be withdrawn must be supplied as part of the e-Filed return.
The RequestedPaymentDate in the StatePayment section of the FinancialTranscation is
used to indicate an ACH Debit's Effective Date. Holidays and weekends are not valid
effective dates. The effective date must be at least three business days after the filing date
- any effective date not satisfying this requirement is unacceptable.
For example, a taxpayer files on February 11, 2011, the earliest effective date is February
16, 2011.
Oklahoma does not accept International ACH Transactions (IAT) at this time. If the IAT
indicator field is marked, the taxpayer should submit the balance due by another means.
• Electronic Funds Transfer (EFT) ACH Credit or Debit.
Taxpayers can choose to have their payment directly withdrawn from their checking or
savings account via the OTC website at www.tax.ok.gov. The taxpayer would click on
link “payment options” and then “E-Check”.
• Credit Card Payment
Credit cards accepted are Discover, Master Card, Visa and American Express. Credit
card payments may be made via the OTC website at www.tax.ok.gov. The taxpayer
would click on link “payment options” and then “Credit Cards”. Payments can also be
made by calling 1 (866) 289-0455.
• Check or money order accompanied by payment Form EF-V
Checks or money orders should accompany the Form EF-V and be mailed to the OTC at
the following address:
Oklahoma Tax Commission
Electronic Filing
PO Box 26890
Oklahoma City OK 73126-0890
Do not mail a copy of the tax return with the payment.
If the taxpayer is making a partial payment, a billing coupon will be sent to the taxpayer for the
balance due at which time the taxpayer will have the option of paying the remaining balance in
full, or making monthly payments until the balance is paid in full.
12
Refund Returns
Taxpayers have four options when their return shows an overpayment of tax. They may elect to
have any or all of their overpayment:
• Direct deposited into a checking or savings account. The bank routing and account numbers
must be supplied as part of the e-Filed return. Note: Oklahoma will only deposit into one
account per tax return.
• Due to changes in the electronic banking rules, the Oklahoma Tax Commission will no longer
allow direct deposits to or through foreign financial institutions or if the taxpayer has a
foreign address on the tax return. The taxpayer will be issued a paper check.
• Refunded in the form of a paper refund check
• Applied to next year’s estimated tax
• Donated to a variety of Oklahoma organizations. See the 512 instructions for a list of the
organizations.
Taxpayers should first confirm acknowledgment of their Oklahoma return with their practitioner
or transmitter. Tax preparers should wait at least 14 days from the date of acknowledgment for a
paper refund or 10 days for a direct deposit before contacting the OTC about their refund.
Changes to Electronic Returns
After an electronic return is acknowledged as accepted, it cannot be recalled, intercepted or
changed in any manner. If either the ERO or taxpayer wishes to change any entries on an
accepted electronic return, an amended paper return must be filed.
Name, address or FEIN changes may be made by contacting the Corporate Section of our
Compliance Division. Contact the Section by phone at (405) 521-3126, fax at (405) 522-3283, or
by mail at Oklahoma Tax Commission, Corporate-Compliance Division, PO Box 269054,
Oklahoma City OK 73126-9054. Be sure and include your name and telephone number on any
correspondence.
13
Responsibilities of Electronic Filers
The guidelines in IRS Publications must be followed for Oklahoma Electronic Filing.
• Penalties for Disclosure or Use of Information
Guidelines outlined in Section 6, IRS Revenue Procedure 93-8 should be followed, as
well as Title 68, Section 205 Oklahoma Statutes.
• Penalties for Late Filing, Late Payment and Fraudulent Returns
This provision provides due notice that all penalties, interest and criminal provisions
which are applicable for paper returns, are also applicable for electronic returns.
Specifically, penalty and interest on tax for late filing and/or late payment will be
assessed.
Penalties will be assessed for any person filing a fraudulent or misleading return.
Additionally any person who willfully subscribes or presents a fraudulent return will be
subject to prosecution and the penalties.
* Other criminal provisions will be applicable to the extent that a person attempts
to commit forgery and falsify signatures on any electronic filing form or check
* Any attempt to pass bad checks for payment of taxes will be prosecuted.
• Advertising Standards
Guidelines in IRS Publications and Revenue Procedure 93-8, Sec 12.01 through 03 and
05 through 09 must be followed for Oklahoma MeF, as though references to the IRS or
Service were references to the OTC, State of Oklahoma, or the State and references to the
FMS or Treasury Seals were references to the State of Oklahoma Seal.
• Monitoring and Suspension of an Electronic Filer
The OTC will monitor electronic filers for conformity to this publication. Under the MeF
Program, the OTC can recommend suspension of an electronic filer for due cause through
the local IRS District Office Coordinator.
Note: Warning letters, suspension and rejection from electronic filing will be administered by the
local IRS District Director.

neutral to the State as determined by the Oklahoma Tax Commission. Previously, the amount
of such credit was 10% or 25% of approved costs. Revenue neutral means the amount by
which increased tax revenues from the tourism attraction project or the film, digital media or
music production and development facility will exceed the credit.
􀂾 Proof of expenditures is required prior to the Tax Commission issuing a tax credit
memorandum to the approved company which may be satisfied by a report from an
independent certified public account.

Acceptance and Participation
EROs and transmitters must be approved with the IRS in order to submit Fed/State or State
Standalone returns. You do not need to register with the Oklahoma Tax Commission. Upon IRS
approval for electronic filing, you are automatically approved for Oklahoma.
Software Developers must register by completing Form D-104 “Software Developer Information
Sheet For Electronic Filing of Corporate Income Tax Returns (Form 512)”. You will receive a
confirmation that we have received your information. Once you have received the confirmation
you may then transmit your test returns. You may download test returns from our website
www.tax.ok.gov under the Developer/Preparer Info link.

Types of Returns Accepted
• Linked (Fed/State)
The Federal and state submissions do not have to be transmitted to MeF together. A state
submission can be linked to the Federal submission by including the Submission ID of the
Federal return in the state manifest. If the state submission is linked to a Federal submission (also
referred to as a Fed/State return), the IRS will check to see if there is an accepted Federal
submission under that Submission ID.
If there is not an accepted Federal return, the IRS will deny the state submission and an
acknowledgement will be sent. Oklahoma will have no knowledge that the state return was
denied (rejected ) by the IRS.
If there is an accepted Federal return under that Submission ID, then the IRS will do minimal
validation on the state submission and pass along to the state what the ERO/Transmitter sends in
the State submission. Oklahoma will generate the acknowledgement for the Oklahoma return and
send it to the MeF system for the transmitter to retrieve.
• Unlinked (State Standalone)
If the ERO/Transmitter does not link the state return to a previously-accepted Federal return (also
referred to as State Standalone), the IRS will perform minimal validation and will pass along to
the state the entire state submission that was sent in by the ERO/taxpayer. The state return is
made up of the Oklahoma return and applicable Federal return; the taxpayer is required to provide
both components. Oklahoma will generate the acknowledgement for the Oklahoma return and
send it to the MeF system for the transmitter to retrieve.

What Can be Transmitted Electronically
The Oklahoma electronic return will consist of data transmitted as well as supporting PDFs. In
total, an electronic return contains the same information as a comparable return filed entirely on
paper.
The following is a list of all of the XML forms that Oklahoma accepts electronically. Software
Developers are not required to support all of the supplemental forms that Oklahoma accepts
electronically.
Income Tax Return
• Form 512 - Oklahoma Corporate Income Tax Return
Supplemental Forms
• Form 512-TI – Computation of Oklahoma Consolidated Taxable Income
• Form 511CR – Other Credits Form
• Form 561C – Oklahoma Capital Gain Deduction for Corporations Filing Form 512
• Form 506 – Investment/New Jobs Credit
Note: Any of the above supplemental forms that a Developer does not support as XML data
should be attached as pdf documents.
Attachments to the Electronic Return
The tax return may also include non-XML documents, known as “binary attachments”, submitted
in PDF format. These attachments include items from the following sources:
• Form/Schedule not supported – any Oklahoma forms or schedules which are required
to be filed with the return, but not supported in XML format.
• Supporting documentation – any supporting documentation required to be submitted
with a form.
• Additional information – any additional information that needs to be filed with the
return.
Approved MeF tax preparation software should provide the necessary instructions for creating,
scanning or exporting documents in PDF format and submitting these documents as attachments
that are required by Oklahoma and IRS publications, Code, and/or Regulations. Preparers will
create the binary attachments as pdf documents and submit them as electronic files attached to the
MeF return. Check with your software provider to see if your software will support binary
attachments.
9
Copy of Federal Return Required
The complete Federal return and the necessary supporting schedules as submitted to the IRS are
required to be submitted in XML and PDF format along with the Oklahoma return. If the
taxpayer is included in the Federal return of a consolidated group, a copy of the pro-forma
Federal return for the company must be included along with the first four pages of the
consolidated Federal return and the consolidating income statement, balance sheet and schedule
M-1/M-3 including applicable detailed schedules.
What Cannot be Transmitted Electronically
Oklahoma follows the IRS guidelines for MeF exclusions (Refer to IRS Publication 4164). In
addition to the IRS guidelines, the following types of returns are excluded from electronic filing:
• Amended returns
• Subsequent return beginning in same tax year – Oklahoma will only accept one return
each filing season, any subsequent filings such as an additional short year return must
be filed by paper.
• Returns for a tax year prior to 2009. You must pass testing in order to e-file prior year
returns.
• Filings that are a duplicate to a paper filed return.
• Returns with cent entries
Signature Document (Form EF)
The Form EF must be completed and signed by all required parties.
• The original is to be retained by the ERO, along with a copy of the e-Filed return, for 3
years and made available to the Oklahoma Tax Commission upon request. All EROs will
be subject to periodic reviews by the OTC to ensure the paperwork is being retained.
• The taxpayer must be provided with a copy of the Form EF along with documentation of
all completed Oklahoma forms and schedules filed for the taxpayer. This documentation
may be furnished on official Oklahoma forms, on copies of official forms, or on software
designed forms that have been approved by the Oklahoma Tax Commission.
Entry of the Taxpayer’s Personal Identification Number (PIN) in the electronic filing
process operated by the IRS shall service as an “electronic signature”. Entry of the
taxpayer’s PIN as signature will only be allowed on a linked (Fed/State) electronically-filed
return. Use of a PIN will not be allowed on an unlinked (State Standalone) return.
10
Acknowledgement System
Oklahoma generates an acknowledgement of acceptance for all returns received. Oklahoma does
not reject e-Filed returns. If an electronic acknowledgement has not been received within 48
hours of our scheduled retrieval process for any transmitted return, the ERO should contact
Oklahoma’s E-File Coordinator for further instructions. It is the responsibility of the ERO to
ensure that every return filed electronically is acknowledged as accepted.
Timeliness of Filing
All prescribed due dates for filing of returns apply to MeF returns. If any due date falls on a
Saturday, Sunday or legal holiday when the Oklahoma Tax Commission’s offices are closed, the
return must be filed by the next business day.
The receipt of an electronic postmark will provide taxpayers with confidence that they have filed
their return timely. When the date of the electronic postmark is on or before the prescribed due
date but the return is received by Oklahoma after the due date, the date of the electronic postmark
is considered the date of filing.
11
Balance Due Returns
Taxpayers who file their return electronically can elect to pay their balance due by four different
methods. The taxpayer is responsible for paying the amount due to the OTC when a return is filed
or no later than the original due date.
• Direct debit (electronic funds withdrawal), for a full or partial payment when filing their
return and choose an effective date.
Taxpayers may have their payments directly withdrawn from their checking or savings
account. The bank routing and account numbers, the amount to be withdrawn and the
date the funds are to be withdrawn must be supplied as part of the e-Filed return.
The RequestedPaymentDate in the StatePayment section of the FinancialTranscation is
used to indicate an ACH Debit's Effective Date. Holidays and weekends are not valid
effective dates. The effective date must be at least three business days after the filing date
- any effective date not satisfying this requirement is unacceptable.
For example, a taxpayer files on February 11, 2011, the earliest effective date is February
16, 2011.
Oklahoma does not accept International ACH Transactions (IAT) at this time. If the IAT
indicator field is marked, the taxpayer should submit the balance due by another means.
• Electronic Funds Transfer (EFT) ACH Credit or Debit.
Taxpayers can choose to have their payment directly withdrawn from their checking or
savings account via the OTC website at www.tax.ok.gov. The taxpayer would click on
link “payment options” and then “E-Check”.
• Credit Card Payment
Credit cards accepted are Discover, Master Card, Visa and American Express. Credit
card payments may be made via the OTC website at www.tax.ok.gov. The taxpayer
would click on link “payment options” and then “Credit Cards”. Payments can also be
made by calling 1 (866) 289-0455.
• Check or money order accompanied by payment Form EF-V
Checks or money orders should accompany the Form EF-V and be mailed to the OTC at
the following address:
Oklahoma Tax Commission
Electronic Filing
PO Box 26890
Oklahoma City OK 73126-0890
Do not mail a copy of the tax return with the payment.
If the taxpayer is making a partial payment, a billing coupon will be sent to the taxpayer for the
balance due at which time the taxpayer will have the option of paying the remaining balance in
full, or making monthly payments until the balance is paid in full.
12
Refund Returns
Taxpayers have four options when their return shows an overpayment of tax. They may elect to
have any or all of their overpayment:
• Direct deposited into a checking or savings account. The bank routing and account numbers
must be supplied as part of the e-Filed return. Note: Oklahoma will only deposit into one
account per tax return.
• Due to changes in the electronic banking rules, the Oklahoma Tax Commission will no longer
allow direct deposits to or through foreign financial institutions or if the taxpayer has a
foreign address on the tax return. The taxpayer will be issued a paper check.
• Refunded in the form of a paper refund check
• Applied to next year’s estimated tax
• Donated to a variety of Oklahoma organizations. See the 512 instructions for a list of the
organizations.
Taxpayers should first confirm acknowledgment of their Oklahoma return with their practitioner
or transmitter. Tax preparers should wait at least 14 days from the date of acknowledgment for a
paper refund or 10 days for a direct deposit before contacting the OTC about their refund.
Changes to Electronic Returns
After an electronic return is acknowledged as accepted, it cannot be recalled, intercepted or
changed in any manner. If either the ERO or taxpayer wishes to change any entries on an
accepted electronic return, an amended paper return must be filed.
Name, address or FEIN changes may be made by contacting the Corporate Section of our
Compliance Division. Contact the Section by phone at (405) 521-3126, fax at (405) 522-3283, or
by mail at Oklahoma Tax Commission, Corporate-Compliance Division, PO Box 269054,
Oklahoma City OK 73126-9054. Be sure and include your name and telephone number on any
correspondence.

• Monitoring and Suspension of an Electronic Filer
The OTC will monitor electronic filers for conformity to this publication. Under the MeF
Program, the OTC can recommend suspension of an electronic filer for due cause through
the local IRS District Office Coordinator.
Note: Warning letters, suspension and rejection from electronic filing will be administered by the
local IRS District Director.
